    Abstract
  • For entire-body special-shaped component such as multi-branch entire-body special-shaped hollow composite material tressel, the complex curved surface construction and continuity in laying fiber become obstacle in CAD. So block-modeling and grid-refining are used to control the direction of the surface and generate equal-space grids. As a result, it is easier to generate the grids.The order and direction of the board layer are changed, the mechanical properties is analyzed and the design of component is optimized by means of testing and simulating with finite element software. The entire-body special-shaped racing bicycle,shaped by pouring resin into sewing exemplar, is proved to be acceptable after experiment and checking.This means that the method is practicable and can be used to design components of either aerostat and space craft or civil product.
